FLU E-CLEANER.

SPECIFICATION forming part of Letters Patent No. 477,957, dated June 28,1892. Application filed September 22, 1891. Serial No. 406,464:- (Nomodel.)

To all whom it may concern.-

Be it known that I, WVALTER PHARR, of Barnum, in the county of Polk andState of Texas, have invented a new and useful Improvement inFlue-Cleaners, of which the following is a specification.

My invention is an improved flue-cleaner; and it consists in certainnovel constructions and combinations of parts, as will be hereinafterdescribed, and pointed out in the claims.

In the drawings, Figure l is a side View of the device, showing thecleaner-head compressed. Fig. 2 is a side view, part in section, showingthe cleaner-head expanded. Fig. 3 is a longitudinal section of thedevice, and Fig. 4 is a detail view of the cleaner-head.

My improved flue-cleaner comprises a plurality of segmental serratedsections A and spring-supports B therefor, whereby they are given anoutward tension. In rear of such sections A, I provide thescraper-sections C for pushing out of' the flue the material cut off bythe sections A. The sections A and O are arranged at, respectively, theouter and inner ends of semi -cylindrical sections D, which are securedto the outer ends of the spring-arms B. These parts A A, C C, and D Dconstitute the cleaner-head. The arms B are formed by bifurcating theend of the handle-rod and bending such arms out, so that they divergegradually from the point of separation toward their outer ends, wherethey support the cleaner-head sections. The handle-rod is thus providedat one end with the cleaner-head and has at its opposite enda suitablehand-hold E.

In use the cleaner-head may be compressed and inserted in the fine andthen be released to expand to fit snugly in the flue and scraper andclean the same, as desired, the serrations or teeth efiiciently removingall scale and the like and the scraper plates or flanges serving to pushit therefrom. It is preferred to support the handle-rod to slide in ahollow stock F, open at both ends, and the handle-rod projecting at bothends beyond such stock. At the end adjacent to the bifurcated end of thehandle-rod the hollow stock is preferably slightly enlarged to permitthe spring ends to is drawn backward into the stock the springarms arecompressed and the'cleaner-head is so compressed that it will enter theflue. Then by pushing the handle-rod forward and holding the stock thespring-arms will adjust out of the stock and the cleaner-head expand toproperly fit in the flue. To hold the stock and handle-rod in the saidrelation with the head expanded, I provide a latch. This latch is shownas having a pin G, movable through an opening H in the stock into anopening I in the handle-rod when such openings H I register.' This pin Gis supported on one end of a spring-plate g, the opposite end of whichis secured to the handle-rod. It is manifest that instead of forming thespring-arms integral with the handle-rod they might be made separatelyand secured thereto by riveting, welding, or in other suitable manner,and that such construction would to a certain extent be the equivalentof the integral construction shown.

Having thus described my invention, what I claim as new is- 1. Animproved flue-cleaner comprising a hollow stock and the expansiblecleaner-head having spring-arms and a rod on which the stock ismounted,said arms being movable within said stock and out ofone end thereof andarranged to be pressed toward each other by such end of the stock asthey are drawn therein and to expand as they are pushed out of such endof the stock, all substantially as and for the purposes set forth.

2. In a flue-cleaner, substantially as described, the combination of astock having an opening and the expansible cleaner-head comprisingspring-arms and a rod on which the stock is mounted, said arms beingmovable longitudinally in' said opening, such arms being drawn togetherat one end and normally flared at their other or outer ends and adaptedto be compressed by the walls of said opening as they are drawnthereinto, substantially as set forth.

3. A flue-cleaner consisting of a hollow tubular stock open at both endsand a handlerod on which said stock is mounted, said rod movablelongitudinally in said stock and proi truding at one end beyond one endthereof and provided at its opposite end with spring-arms protrudingfrom the other end of the stock and flared at their outer ends, wherebythey m -y be compressed by the engagement of the walls of said end ofthe stock when drawn thereinto, all substantially as and for thepurposes set forth.

4. A flue cleaner comprising the hollow stock and the handle-rod slidingin said stock and having the spring-arms and the cleanersectionsupported thereon, the hollow stock' being mounted on the rod, allsubstantially as and for the purposes set forth.

5. In a flue-cleaner, the combination of the hollow stock having aguide-slot and the handle slidingin the said stock and havinga pin orprojection entering the guide-slot of the stock and provided with springarms having the cleaner-head sections, the hollow stock being hold andthe other being bifurcated, forming spring-arms supportingcleaner-sections, substantially as and for the purposes set forth.

7. In a flue-cleaner,acleaner-head comprising two semi-cylindricalsections, each provided at one end with outwardly-projected serrationsor teeth and at the other end with an outwardly-proj ected flange orscraper-plate having its edge uninterrupted or unserrated, allsubstantially as and for the purposes set forth.

8. The combination,in a flue-cleaner, of the hollow stock, theexpansible cleaner-head having its support movable in the said stock,and the latch by which to hold such head in its expanded position,substantially as set forth.

9. The improved flue-cleaner consisting of the hollow stock having anopening for the latch-pin, the handle-rod sliding in the said stock andhaving an opening movable into register with the opening in the stockand also provided with spring-arms supporting the segmentalcleaning-sections, and the latch comprising a spring-shank fixed at oneend and provided at its other or free end with a pin movable into theopenings in the stock and handle-rod when such openings are registered,substantially as set forth.
